A cup of coffee a day did not worsen atrial fibrillation (AF) in adults recovering from electrical cardioversion, and it may even lower the likelihood of recurrent arrhythmia, according to new ...

A multicenter randomized clinical trial found that moderate caffeinated coffee intake after cardioversion significantly lowered the recurrence of atrial fibrillation or flutter compared with ...

When people feel emotionally close, their bodies may start to act in tandem. A new study published in Biological Psychology offers evidence that this alignment can reach the level of the heart.

Abstract: Phase-locked loop (PLL)-synchronized inverters, characterized by low inertia and weak damping, are prone to loss of synchronization (LOS) during and after low-voltage grid faults. To ...

Abstract: We demonstrate optical arbitrary waveform generation using self-injection-locked Kerr micro-combs that are synchronized to an electronic clock via a closed-loop control. We show 200 GBd ...
